The keyboard has the same ergonomics and feel as the LX 500. There's no point in repeating ourselves: we're won over! Apart from the looks, the layout of the direct-access and multimedia keys is a little different. The function keys are rectangular and maybe just a tad easier to use, and the play/pause and volume keys also seem better placed. The volume is controlled by a turn button - a practical choice. The "Cruise Control" scroll wheel on the left is heftier and wider, and it's a tilt wheel like the one on the mouse. It's easier to manipulate and more precise. It also has two rapid-scrolling buttons and a zoom function.
